To all whom it may concern:

Be itknown that I,.NEWTON (J. WELLS, a citizen "of" the United States of America, residing atGlob e,in the county of Gila and seas of Arizona, has invented certain new and useful Improvements in WedgeCutting Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention has for its principal ob-- ject the production of a machine whereby the operator may cut wedges Without any danger of cutting his hands, or having splinters fly in his face, when using the circular saw.

Another object of this invention is th production of a simple and efficient device which may be easily attached to a saw table to cut wedges of difi'erent sizes.

With these and other objects in view this invention consists of certain novel combinations and arrangements of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings Figure 1 is a perspective View of the device.

Fig. 2 is a top plan view of the device. Fig. 3 is a section taken on line 3-3 of Fig. 2, showing the device attached to the work table.

Fig. 4 is a detail perspective view of the wedge guide with the necessary operating parts.

Fig. 5 is a detail perspective view of the wedge.

Fig. 6 is a section taken on the line 6-6 of Fig. 2 looking in the direction of the arrow.

By referring to the accompanying drawings by numerals, it will be seen that 1 designates the bench which is provided with i an elongated slot2, through which the circular saw 3 passes. This circular saw 3 is mountedupon the shaft 4 and is provided with the usual teeth. 5. The bench 1 is provided with the elongated slot 6, which runs at right angles to the slot2. In the slot 6 there is positioned the bolt 7, upon which is mounted the brace 8, which. brace 8 carries the track 9. Upon the bolt 7 there is provided the thumb nut 10, whereby the track when adjusted in the desired position may be fixedly held in position.

A sliding gage is placedupon the track 9 is clearlyshown in Fig. 3. This slidin pivot pin 21.

gage consists of the depending plate and the top platejyl2. These plates 11, and 12 "are held apart, by means of the blocks 13. Adjacentthese blocks there are provided the stop block 14, as is clearly shown in Fig.

6. These stop blocks are provided with the body portions 15 and the necks 16. Upon one edge of the top plate 12 there are fixedly mounted the guiding brackets 17 which fit over the track 9, as clearly shown in Fig. 3. Upon the opposite edge there are fixedly carried the guard brackets 18, UPOILWlllCh is mounted the guard 19. This guard 19 is substantially U-shaped in cross section and isadapted to pass over the saw 3, thereby preventing any splinters from flying into the face of the operator.

Between the plates 11 and 12 there is provided the tilting gage 20, which is provided with the pin 21, so that the same may be pivotally mounted between the top and bot tom. plates. This pivot pin 21 passes throughthe apertures 22, as is clearly shown in Fig. 3. Between the plates 11 and 12 there are also provided the stop pins 23. Intermediate the end portions ofthe tilting gage paa ar fes ate. easements. 131, 19118. a

20, there is provided the lever 24, which is i fixedly attached to said tilting gage, by means of the nails or screws 25. This lever 24 is held in pivotal engagement with the rod 26, by means ofthe pm 27. i A spaced distance from the end of this rod 26 there is positioned the operating handle 28. Upon the upper plate 12 there is provided the elongated slot29 through which passes the 28 is carried in either direction in the slot 1 29, the tilting gage 20 will pivot upon the When this device is in operation, the rectangular piece of wood is placed along side the outer edge of the tilting gage 20 and the sliding: gage is adjusted by means of the bolt"? and thenut 10to the desired position, and the sliding gage is passed along the track 9, so that the rectangular piece of wood will come into engagement with the saw 3, after the tilting gage 20 has been placed in the desired position. It

will be seen that therectangular piece of wood will lie along theouter edge of the tilting gage 20 and will abut against the i stop blocks 14, which will prevent the gage 20 from being displaced. It will also be 5 will be seen that the track 9 may be adjusted, and that the sliding gage maybe placed closer QI' farther from the saW 3. 'ItWillbe seen that if a Wedge is desired to be out without having a sharp ppint, then ll-8v the tilting gage 20 may be easily adjusted te the desired pesitien, by means of the handle 28. The hgle sliding gage is .operatedby grasp'ing thekneb 30, so that the sliding gage nay be passed engagement with the saw.

"What I claim is z-- A deviceozfitheclass described, comprising a guide track adjustable toward and from the'plane of'a saw, a sliding gage engaging the track and guided thereby, and a gage member having limited pivotal movement mounted onthe sliding gage.

In testirneny whereof I hereunto aflix my signature.
